Kepler correctly proposed that the planets orbited the sun in orbits. a. circular c. linear b. elliptical d. spherical

The correct answer is B. Elliptical

Explanation:

Johannes Kepler was one of the most important astronomers during the scientific revolution that took place in the 17th century. Kepler is mainly recognized due to his proposals about the motion of planets that he registered in books such as the Astronomia nova. One of the most important ideas of Kepler was that planets orbited the sun in elliptical orbits, rather than in circular orbits as it was believed before Kepler's proposal. Additionally, Kepler got to this conclusion based on observations and models that prove orbits could not be circular. Thus, Kepler correctly proposed that the planets orbited the sun in elliptical orbits.
